How much does it cost to paint a room in the UK?

Updated October 2026

Quick answer: A straightforward medium room often needs around £70–£160 of DIY materials for walls and ceiling, or roughly £350–£650 supplied and painted by a decorator. Damaged walls, intricate woodwork and extra coats increase the total. Floor area alone cannot price the work: wall height, perimeter and preparation matter just as much.

Typical room painting costs in 2026

The table assumes accessible rooms with sound previously painted walls, an ordinary ceiling and two coats of standard emulsion. Figures are typical UK ranges for October 2026, including VAT where charged, and are planning estimates rather than quotes. They exclude stripping wallpaper, full plaster repairs, doors, skirting and major furniture removal.

A high-quality washable finish or a dramatic colour change can push materials above these bands. Equally, a DIYer who already owns clean brushes, rollers and dust sheets may spend less on sundries. A decorator's material price includes selection, collection and handling as well as the contents of the tin, so it need not match a retail basket.

Worked example: a 4m × 3m bedroom

Assume a 2.4m ceiling height, one 1.8m² door and a 1.4m² window. The paint cost calculator lets you enter measurements, openings, coats and coverage; use the chosen paint's figure rather than relying on floor area. It estimates walls, so calculate the ceiling separately.

1. Perimeter is 2 × (4 + 3) = 14m.
2. Gross wall area is 14 × 2.4 = 33.6m².
3. Deduct 3.2m² of openings to get 30.4m² of walls.
4. Two wall coats at 12m²/L need 30.4 × 2 ÷ 12 = 5.07 litres.
5. The 12m² ceiling needs 12 × 2 ÷ 12 = 2 litres for two coats.

At an illustrative £24 per 2.5L wall tin, three tins cost £72. A 2.5L ceiling tin at £18 and £28 of filler, abrasives and roller supplies bring the DIY material total to £118. Separate colours create separate purchase rounding; buying 7.5 litres in total does not mean every litre is usable on every surface.

If a decorator allows 1.5 days at £240 per day, labour is £360. Adding the same £118 material allowance gives £478. The decorator may price the job as a whole rather than bill exactly 1.5 days, but this arithmetic helps explain a mid-range room total.

Decorator day rates and time on site

A typical UK planning range is around £150–£350 per day for a decorator, with location, experience, business costs and VAT affecting the figure. London and difficult-access work may sit higher. A rate alone says little about value unless you know what preparation and finish it includes.

A plain room may require one to two working days, but drying intervals can spread visits across longer calendar time. Ceiling stains, heavy filling, dark colours, multiple doors or detailed cornicing add work. On a small job, travel and setup create a minimum charge even if the final coat itself takes only a few hours.

Ask for the surfaces and preparation to be described in writing. “Paint bedroom” could mean walls only, while another price includes ceiling, skirting, door frames, sanding and caulk. Confirm whether paint, parking, furniture protection, cleanup and VAT are included before comparing totals.

Standard versus premium paint

Premium price does not automatically mean fewer coats. Compare stated coverage, opacity, sheen, cleaning suitability and required preparation. A specialist finish may be sensible near fingerprints and cooking splashes, while an ordinary bedroom may not need that specification. Tester pots help avoid repainting a whole room because the colour looks different in its actual light.

What changes the price most?

Preparation: removing flaking paint, repairing cracks and sanding rough filler often takes longer than applying emulsion. New plaster needs the manufacturer's specified first-coat system and adequate drying. Stains may need a suitable blocker; extra emulsion alone may not stop them reappearing.

Height and detail: tall walls, stairwells, beams and many small edges reduce productivity. Colour: a strong colour change may need an additional coat, so calculate each coat rather than assuming two will always suffice. Woodwork: doors and mouldings introduce different coatings, preparation and drying intervals.

Occupation: a clear empty room is easier to work in than one full of furniture. Moving items yourself can help if agreed in advance, but do not strip protective coverings or rush the decorator's drying sequence to save a small amount of time.

Keep costs down without spoiling the finish

Measure first, clean sound surfaces and tackle small repairs before opening paint. Budget for full tins after calculating litres, and keep a labelled remainder for touch-ups. An unnecessary extra tin is wasted money, but running short can delay the job or create a colour difference between purchases.

Read how many coats of paint you need before choosing the coat count. Use painting mistakes that waste money as a preparation checklist. Correct coverage and a clean substrate usually improve the result more than buying the most expensive paint in the shop.
